Nock Help

Hey Hunters, retired the Hoyt D riser and Splured on a new Bowtech 340. Been hunting with the bow now and really like it. I'm having one problem while practacing and do not want it to happen when I have that Booner in front of me. Once in a while the arrow falls off the string when drawing. Are there any hidden secrets on tightening the arrow nocks to the string? I tried wrapping some serving around the string between the "loop" but it just got worse. I am now pinching the nocks before I attach them and shoot. They are Cabela's carbon hunter arrows with standard nocks. Any simple solutions out there before I switch nocks?
